About
On some older benders, the Mitsubishi drives power down when E-Stop is pressed. This approach causes the Feed and Rotate axes to loose the HOME status in the I2T modules when the E-Stop is pressed.
Since CNC Bender software monitors the home state as a way to predict servo module health, it is necessary to keep the Mitsubishi drivers powered - even when the E-Stop is activated.
WARNING! |
STEP 1: Check the State of the Drives at E-Stop
Set MASTER POWER ON, Press the E-Stop, then examine the drives LED screens. If they are blank, then the drives are off, and you will need to perform this wiring change during a CNC Bender upgrade.

STEP 2: Find Three Wires
Find the three wires entering the top left side of the white fuse buse to the left of the Feed drives.
- The wires will be labelled 3L1, 3L2, and 3L3.
- Trace those wires to the M-2 contactor. (Find the other end.)
STEP 3: Reroute the Wires
- Reroute these three ends to the top of the M-1 contactor.
- Be sure to place the wires into the proper terminal point (1, 2, or 3).
- If there are other wires in the bottom of the M-2 contactor, then leave them in place.
- Leave the wires that are in the top of M-1 in place. (Double up the 1L1, 1L2, 1L3 and the three "3" wires.)
STEP 4: TEST
- Apply power to the bender (at the main breaker switch outside the bender)
- Press the E-Stop
- The drive should stay powered like this:
